Radio Shack has discontinued their Accurian hst6000 HDTV receiver. You may still be able to find one at a store for $89. It has hdmi output; but you can get a cable to adapt from hdmi -> dvi at monoprice.com for short money.http://www.radioshack.com/product/index.jsp?productId=2104191&cp=2032057&f=Taxonomy%2FRSK%2F2032057&categoryId=2032057&kwCatId=2032057&kw=hdmi&parentPage=search
You can find at least one review on this box via google. The main complaint that people have had is that the remote that comes with it must be aimed to work. That is easy to fix with an aftermarket universal remote; I use a Harmony and their database has the codes in it so it's a quick download.
Amazon also had an RCA stb for about $150 last month; I don't know if it had dvi output or not.
